Rise Park: your questions answered
Do you cover Rise Park for external mastic?
Yes. We work across London and the South East, and Rise Park is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear quote.
I let a flat near Gidea Park station. Can you help?
Yes. We work for landlords and agents as well as householders, and several properties can go on one quote. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
How long does external mastic take?
As a guide, most jobs take anything from a few hours to several days, depending on the building. Larger jobs naturally take longer.
What do you need from me for a quote?
A short description and the location. We’ll ask anything else we need to know.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint.
How often do external joints need resealing?
It varies from wall to wall: joints on exposed walls or with a lot of movement age sooner. Check them each year and reseal when they split or harden. Every job carries our one-year guarantee.
Is it OK to seal over old sealant?
No, it will not last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
What colours does the sealant come in?
We choose a sealant colour to suit the brick, stone or render. There’s a wide choice of exterior colours.
External mastic in Rise Park
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two. We work on façade panels, copings & trims and render & cladding joints, and common reasons people get in touch are movement joints filled with mortar instead of sealant and damp patches traced to an open external joint.
Working on the outside of a London home means planning access: shared paths, upper floors and parking. In Rise Park, joints up high may need ladders or other access, which is worth talking through when you book.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or drop us an email.

What we’re called out for in Rise Park
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
Look out for these signs:
- Joints pointed up with cement by mistake
- Joints where the bead has come unstuck
- Plants rooting in failed movement joints
- Weathered mastic that no longer stretches
As a London address, Rise Park can be tricky for parking: let us know about parking bays, permits or a driveway.
What your quote should include
- Is the old sealant removed completely?
- Whether the sealant suits the joint
- Is VAT in the price?
- What happens if the job turns out different
Landlords, agents and businesses in Rise Park
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Letting agents and landlords in Rise Park can book us as well as householders. Sealant work between tenants is a simple way to keep a property in good order.
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Avoid pressure-washing directly into sealant joints
- Keep soil, plants and ivy away from the joints
- Get split or bare joints resealed while the damage is small
- Check the sealant is paintable before painting near it
Only paint over the joint if we’ve confirmed the sealant can take paint. Many exterior sealants are not designed to be painted.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
Why deal with it now?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Rise Park, the repair is bigger than the sealant job would have been.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we’ll explain what it covers.

What happens on the day
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to several days, depending on the building. In Rise Park, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Getting ready for the visit
- Tell us if parking is tricky
- Plan for the work area to be out of bounds to pets and children
- Let us know if you’ve seen damp or leaks
How to get a quote

Advice
DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
What external mastic looks like in Rise Park
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Hare Hall (about 1.3 miles south-east) are a reminder that the area around Rise Park has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
If you look after a building such as Rise Park Infant School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you live in an older home near St James, an extension built onto an older house moves differently, and the joint between them takes the strain.
